![]() ![]() Mornsun's railway DC/DC power supplies meet the requirements of EN 50155 and Category 1 Class B, with operating temperature range-40 ℃ ~ 85 ℃/105℃, up to 3000VAC reinforced insulation. Because of the uncertainty of vehicle batteries, reinforced insulation is needed to ensure the smooth operation of vehicle electronic equipment. Mornsun ensures the reliability of the product through reliability tests of High-Low Temperature Test and Damp-Heat Test and provides you with high performance solutions.ģ. Trains have to work in harsh railway conditions all year-round, from the hot equator to cold ice field, so the working temperature range of the vehicle battery also needs to be able to adapt to extreme cold and heat. Railway vehicles are likely to be vulnerable to shock and vibration during driving, so random shock and vibration tests need to be carried out when installing electronic equipment.Ģ. For example,with the increase of altitude, the insulation performance and heat dissipation performance of power supply productsįor vehicle electronic equipment applications, in order to avoid failures caused by potential differences, electromagnetic compatibility, personal safety, and external control failures, the following requirements need to be taken into account:ġ. Rapid development of electronic technology and more and more extensive applications of railway power supplies, the working environment is getting In addition, the environment of railway applicationsĬan be very harsh, so it is required to prove that the module can reach the standard by vibration/shock test to ensure that the anti-vibration andĪnti-impact performance of the module can meet EN50155 and the requirement of Category 1 Class B.ĭC/DC power converters applied in railway power supply systems should equip with wide input voltages and operating temperature ranges. Mornsun can provide standard DC/DCĬonverter modules with different input ranges for different battery power supply railway systems. The working environment and battery power supply in the railway transportation system are relatively special. ![]()
